Embodiments of the present invention

[0023] To enable those skilled in the art to more clearly understand this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0024] As people's demands for living standards and quality of life continue to rise, they are also demanding higher standards for the sterilization effects of cleaning equipment such as robot vacuums, robot mops, or floor scrubbers.

[0025] This disclosure provides an electrolysis device and a cleaning equipment, which aims to at least partially solve the technical problems of high cost, inconvenience of use, and poor disinfection effect of obtaining disinfection water in related technologies, so as to reduce the user's burden and cost and improve the user experience.

[0026] According to some embodiments of this disclosure, an electrolysis device is provided, which is installed in a cleaning device. The electrolysis device includes a housing and an electrode assembly; the housing is provided with an inlet and an outlet, allowing cleaning water to be injected into the housing through the inlet and discharged through the outlet. The electrode assembly is disposed in the housing, so that the cleaning water can cover the surface of the electrode assembly. When the electrode assembly is energized, it electrolyzes the cleaning water in the housing to produce disinfectant. The disinfectant, along with the cleaning water, flows out from the outlet of the housing to act on the surface to be cleaned. This allows the cleaning device to have a disinfection function without the need for an additional sterilization device (disinfectant and / or anion-releasing device) in the water tank; the disinfection concentration is uniform, the disinfection effect is good, and it does not increase the user's burden or cost, thus improving the user experience and demonstrating excellent practicality. The cleaning water can be tap water or purified water; this disclosure does not limit this. Further details of the electrolysis device are now described with reference to the accompanying drawings.

[0027] Figure 1 shows a schematic diagram of the electrolysis apparatus 10 according to some embodiments of the present disclosure. Referring to Figure 1, in one embodiment, the housing 100 is generally square in shape. The inlet 101 and outlet 102 are disposed on the same side wall of the housing 100 along its height. The inlet 101 is located below the outlet 102, so that cleaning water can be stored within the housing 100, and the electrode assembly can be energized at any time to electrolyze the cleaning water within the housing into disinfectant agents. In another embodiment, the housing 100 may also have a columnar structure, with the water outlet 102 located at the top and the water inlet 101 located at the bottom; alternatively, the water inlet 101 and the water outlet 102 may be located on two different side walls of the housing 100, for example, on two opposite side walls of the housing 100, or on two adjacent side walls of the housing 100. This disclosure does not impose any limitations on this. In other embodiments, the water inlet 101 is located above the water outlet 102. This arrangement allows the cleaning water inside the housing 100 to be discharged from the water outlet as much as possible, keeping the inside of the housing 100 dry and clean, preventing bacterial growth inside the housing 100 during long-term non-use, avoiding corrosion, and thus extending its service life.

[0028] In some embodiments, referring to FIG1, a connecting ear plate 109 is provided on the side of the housing 100. The connecting ear plate 109 can be integrally formed with the housing 100. Two connecting ear plates 109 can be provided, with the two connecting ear plates 109 respectively provided on both sides of the housing 100. In other embodiments, only one connecting ear plate 109 can be provided, that is, a connecting ear plate 109 is provided only on one side of the housing 100. The connecting ear plate 109 can be provided with a connecting hole 110 to fix the connecting ear plate to the cleaning equipment by bolts or other connecting parts, thereby fixing the housing 100 to the cleaning equipment. The shape of the connecting ear plate 109 is not limited to the shape shown in FIG1, and can be any shape that is convenient for fixing the housing 100.

[0029] Figure 2 shows an exploded view of Figure 1. Referring to Figures 1 and 2, in one embodiment, the housing 100 includes a bottom shell 103 and a top cover 104, with the top cover 104 connected to the bottom shell 103, so that the bottom shell 103 and the top cover 104 form a water storage cavity. Specifically, the edges of the bottom shell 103 and the top cover 104 are provided with interlocking bosses and grooves, and a sealing element 105 is provided between the edges of the bottom shell 103 and the top cover 104 to ensure a seal between the bottom shell 103 and the top cover 104 and to prevent water leakage at the joint between the bottom shell 103 and the top cover 104.

[0030] Figure 3 shows a schematic diagram of the bottom shell in Figure 2. Referring to Figures 2 and 3, a support member 106 is provided on the inner wall of the housing 100. This support member 106 supports the electrode assembly 200, providing both support and pressure for the electrode assembly 200, and also creating a gap between the electrode assembly 200 and the side wall of the housing 100 to facilitate the flow of cleaning water within the housing 100. In one embodiment, support members 106 are provided on the inner walls of both the bottom shell 103 and the top cover 104 of the housing 100. The support member 106 can be a structure adapted to the top cover 104 or the bottom shell 103, such as a square or columnar structure. The support member 106 can be integrally formed on the inner wall of the housing 100, or it can be arranged in rows on the inner wall of the housing 100; or it can be arranged in a grid pattern on the inner wall of the housing 100. This disclosure does not impose any limitations on this. In another embodiment, the aforementioned support member 106 may be provided only on the inner wall of one of the bottom shell 103 and the top cover 104.

[0031] Referring to Figures 2 and 3, a partition 108 is provided inside the housing 100. This partition 108 divides the interior of the housing 100 into two independent chambers: a first chamber 111 and a second chamber 112. The electrode assembly 200 is disposed in the first chamber 111. Cleaning water cannot enter the second chamber 112. A power distribution assembly 400 is disposed in the second chamber 112. The power distribution assembly 400 is connected to the electrode elements 201 of the electrode assembly 200. The power distribution assembly 400 is configured to simultaneously control at least two electrode elements of the electrode assembly 200 to conduct electricity at a voltage range of 1.5V to 36V. According to some embodiments of the electrolysis apparatus of this disclosure, when the power distribution assembly 400 applies a voltage of 1.5V to 36V to each electrode element, the electrolysis equipment can efficiently prepare disinfecting agents, enabling the cleaning equipment to disinfect the surface to be cleaned or the cleaning equipment itself.

[0032] Referring to Figure 2, in one embodiment, the electrolysis device further includes a terminal block 600. The power distribution assembly 400 is connected to the power supply, main control module, or main control circuit board of the cleaning equipment via the terminal block 600. Through the distribution of the power distribution assembly 400, the electrical conduction of the electrode elements 201 of certain electrode assemblies 200 can be selectively controlled, thereby electrolyzing the desired disinfecting agent.

[0033] Figure 4 shows a schematic diagram of a bottom shell with flow channels according to some embodiments of the present disclosure. Referring to Figure 4, a first flow channel 107 is provided on the inner wall of the housing 100. At least a portion of the first flow channel 107 is curved; this arrangement can extend the flow path of the cleaning water inside the housing 100 to increase the contact area between the cleaning water and the electrode assembly 200, thereby generating more disinfection factors in the cleaning water inside the housing 100, thus improving the disinfection effect of the electrolysis device 10; in addition, the flow direction and shape of the first flow channel 107 can be designed to control the flow direction and flow speed of the cleaning water inside the housing 100, thereby changing the electrolysis efficiency of the electrode assembly 200 and / or the water output of the electrolysis device 10.

[0034] Referring to Figure 4, in one embodiment, the inner wall of the bottom shell 103 of the housing 100 is provided with the aforementioned first flow channel 107. The first flow channel 107 is in the shape of a curved bow or a snake. In another embodiment, the aforementioned first flow channel 107 may also be provided on the inner wall of the top cover 104, and this disclosure does not limit this.

[0035] Additionally, referring to Figure 4, in one embodiment, a second flow channel 113 may also be provided on the support member 106. The second flow channel 113 may be elongated, thereby changing the electrolysis efficiency of the electrode assembly 200 and / or the effluent condition of the electrolysis device 10, so as to improve the disinfection effect of the electrolysis device 10.

[0036] Referring to Figure 2, in one embodiment, the electrode assembly 200 includes two or more electrode elements 201. The two or more electrode elements 201 are spaced apart along the vertical direction from the inlet 101 to the outlet 102, that is, the two or more electrode elements 201 are stacked sequentially along the height direction of the tank 100. When energized, the two or more electrode elements 201 can decompose the cleaning water in the tank 100 to generate disinfectant agents. For example, the two or more electrode elements 201 can electrolyze hydrogen peroxide and / or free hydroxyl groups from the cleaning water. When tap water is used as the source of cleaning water, since tap water contains a certain amount of chlorine, adjacent electrode elements 201 can also electrolyze hypochlorous acid and chlorine dioxide from the tap water.

[0037] Referring to Figures 2 and 3, the cross-sectional shape of the electrode element 201 matches the first chamber, allowing the electrode element 201 to be laid flat within the first chamber. In some embodiments, the electrode element 201 is provided with a perforated portion 202 to allow cleaning water to pass through. In one embodiment, the electrode element 201 is provided with a through-hole structure, the shape of which can be an oval hole, a square hole, or a circular hole, etc. The perforated structure forms the perforated portion 202, the area of ​​which accounts for 55% to 65% of the total area of ​​the electrode element 201. This arrangement ensures the flow rate of cleaning water in adjacent electrode elements 201, thereby adjusting the electrolysis efficiency of the electrode assembly 200 or the water output of the electrolysis device 10. Furthermore, the area ratio of the perforated portion to the area ratio of the electrode element 201 can be adjusted according to the required electrolysis efficiency of the electrode assembly 200 or the water output of the electrolysis device 10.

[0038] It should be noted that the area ratio of the hollow portion 202 of each electrode element 201 may be the same or different; in addition, the hole structure of each electrode element 201 may be the same or different, and this disclosure does not impose any restrictions on this.

[0039] Referring to Figure 2, an odd number of electrode elements 201 are arranged at intervals. The polarities of the electrode elements 201 in the odd-numbered positions are different from those in the even-numbered positions. For example, there are three electrode elements 201, namely the first electrode element 201a, the second electrode element 201b, and the third electrode element 201c arranged sequentially from bottom to top along the height direction. The first electrode element 201a and the third electrode element 201c have the same polarity (e.g., positive), while the second electrode element 201b has a different polarity than the first electrode element 201a and the third electrode element 201c (e.g., the second electrode element 201b is negative, and the first electrode element 201a and the third electrode element 201c are positive). The first electrode element 201a and the second electrode element 201b are electrically connected; and / or, the third electrode element 201c is electrically connected to the second electrode element 201b to electrolyze the cleaning water. This allows for selection of the electrical connection between the first electrode element 201a and the second electrode element 201b, and / or between the third electrode element 201c and the second electrode element 201b, depending on the cleaning environment, to electrolyze different disinfection factors, thereby improving the disinfection effect. In other embodiments, the electrode elements 201 may also be five, seven, etc., and this disclosure does not limit this.

[0040] Referring to Figure 2, the power distribution assembly 400 can simultaneously control the electrical conduction between the first electrode element 201a and the second motor element 201b, and / or between the third electrode element 201c and the second electrode element 201b, with a voltage range of 1.5V to 36V. According to some embodiments of the electrolysis apparatus of this disclosure, when the power distribution assembly 400 applies a voltage of 1.5V to 36V to each electrode element, the electrolysis equipment can efficiently prepare disinfecting agents, enabling the cleaning equipment to disinfect the surface to be cleaned or the cleaning equipment itself.

[0041] Referring to Figure 2, in some embodiments, an insulating element 500 is provided between adjacent electrode elements 201 to prevent short circuits from occurring between electrode elements 201 during electrolysis.

[0042] Figure 5 shows a schematic diagram of the insulating element 500 in Figure 2. Referring to Figure 5, the insulating element 500 can be a frame structure, disposed between the edges of adjacent electrode elements 201. Multiple support ribs 501 can be provided within the insulating element 500. These support ribs 501 can be arranged in parallel or intersecting directions. The shape of the insulating element 500 can also be consistent with that of the electrode elements 201; that is, the insulating element 500 can be plate-shaped and have a perforated structure similar to that of the electrode elements 201, to improve the insulation effect of adjacent electrode elements 201 and prevent short circuits caused by contact between electrode elements 201 during electrolysis.

[0043] Figure 6 shows a schematic diagram of another insulating element 500 according to some embodiments of the present disclosure. Referring to Figure 6, in one embodiment, the insulating element 500 may also be provided with a third flow channel 503 to change the electrolysis efficiency of the electrode assembly 200 and / or the effluent condition of the electrolysis device 10, thereby improving the disinfection effect of the electrolysis device 10.

[0044] Referring to Figure 2, in one embodiment, a catalyst layer 300 is disposed between at least some of the adjacent electrode elements 201. The catalyst layer 300 may include catalyst support elements such as carbon felt, porous ceramics, or aluminosilicates (molecular sieves), and a catalyst is disposed on the surface and / or inside the catalyst support element to form the catalyst layer 300. Under the action of the catalyst layer 300, adjacent electrode elements 201 directly or indirectly electrolyze cleaning water into disinfecting agents such as hydrogen peroxide and / or free hydroxyl groups. For example, the catalyst may be a platinum-based catalyst, a cobalt-based catalyst, a ruthenium-based catalyst, an iridium-based catalyst, or a carbon-oxygen-based catalyst. Under the catalysis of the catalyst, adjacent electrode elements 201 can electrolyze disinfecting agents from cleaning water more quickly or in greater quantities. The electrolyzed substances produced by adjacent electrode elements 201 may be one or more, and this disclosure does not limit this. The provision of a catalyst layer 300 between at least some adjacent electrode elements 201 means that a catalyst layer 300 can be provided between all adjacent electrode elements 201; or, a catalyst layer 300 can be provided only between some adjacent electrode elements 201. The catalyst layer 300 can be clamped between an insulating element 500 and one of two adjacent electrode elements 201 to fix the catalyst layer 300 between adjacent electrode elements 201.

[0045] Referring to Figure 2, a catalyst layer 300 is provided between some adjacent electrode elements 201. When no catalyst layer 300 is provided between some adjacent electrode elements 201, the adjacent electrode elements 201 without the catalyst layer 300, after being energized, can electrolyze the cleaning water to produce ozone, thereby containing ozone in the cleaning water discharged from the tank 100, which also serves a disinfection function. Furthermore, under the control of the power distribution component 400, at least one of the electrode elements 201 with and without the catalyst layer 300 can simultaneously perform electrolysis to prepare the corresponding disinfection factor. That is, the electrolysis product of the first electrode element 201a and the second electrode element 201b conducting electrolysis of the cleaning water is different from the electrolysis product of the third electrode element 201c and the second electrode element 201b conducting electrolysis of the cleaning water.

[0046] Figure 7 shows an exploded schematic diagram of an electrolysis apparatus 10 according to other embodiments of the present disclosure. Referring to Figure 7, in another embodiment, a catalyst layer 300 is provided on at least one side of the electrode element 201. Specifically, a catalyst can be applied to the electrode element 201 by electroplating or coating to form the aforementioned catalyst layer 300. The provision of a catalyst layer 300 on at least one side of the electrode element 201 means that: the catalyst layer 300 is provided on the periphery of the electrode element 201; or, the catalyst layer 300 is provided on the side of the electrode element 201 facing an adjacent electrode element 201; or, the catalyst layer 300 is provided on the side of the electrode element 201 facing away from an adjacent electrode element 201. This disclosure does not impose any limitations on this.

[0047] Figure 8 shows a vertical cross-sectional view of Figure 1. Referring to Figure 8, in one embodiment, the distances between adjacent electrode elements 201 are different. For example, the distance between the first electrode element 201a and the second electrode element 201b is D1, and the distance between the second electrode element 201b and the third electrode element 201c is D2, where D2 < D1, and D2 can be set to 1.2 mm to 1.8 mm. By adjusting the distances between adjacent electrode elements 201, the electrolysis efficiency can be adjusted. This allows for the adjustment of the appropriate electrode spacing according to the different electrolysis products, ensuring the electrolysis efficiency of the electrode assembly 200.

[0048] Figure 9 shows an exploded schematic diagram of the electrolysis apparatus 10 according to some embodiments of the present disclosure. Referring to Figure 9, in another embodiment, two or more electrode elements 201 may also be spaced apart along a vertical direction intersecting the inlet 101 and outlet 102, i.e., two or more electrode elements 201 are horizontally laid out between the inlet 101 and the outlet 102. When the electrode assembly 200 is energized, the energized electrode assembly 200 electrolyzes the cleaning water in the tank 100 to produce disinfecting agents.

[0049] Figure 10 shows a schematic diagram of the electrode assembly 200 in Figure 9. Referring to Figures 9 and 10, at least a portion of two adjacent electrode elements 201 are provided with ribs 203. The ribs 203 of two adjacent electrode elements 201 are located on opposite sides of the two adjacent electrode elements 201 and are staggered, thereby creating flow channels between adjacent electrode elements 201. In the case of generating electrolysis products, the flow rate and direction of water can be controlled, thereby changing the electrolysis efficiency and / or the effluent condition of the electrolysis device 10. In specific implementations, multiple ribs 203 can be integrally formed and connected to opposite sides of two adjacent electrode elements 201. The adjacent ribs 203 are staggered. The ribs 203 of adjacent electrode elements 201 can be located on the same plane or on different planes; this disclosure does not limit this.

[0050] Referring to Figure 10, when there are three or more electrode elements 201, ribs 203 are provided on both sides of the middle electrode element 201. The ribs 203 on both sides of the electrode element 201 are staggered with the ribs 203 of the adjacent electrode elements 201 to form a flow channel between adjacent electrode elements 201.

[0051] Figure 11 shows a schematic diagram of an electrolysis device with a protective tube element according to some embodiments of the present disclosure. Referring to Figure 11, the inlet 101 and outlet 102 of the housing 100 of the electrolysis device 10 are fluidly connected to a water pipe 700. At least a portion of the water pipe 700 connected to the inlet 101 and / or outlet 102 is provided with a protective tube element 800. The protective tube element 800 can prevent the water pipe 700 from bending to a certain extent, thereby allowing cleaning water to flow smoothly into and out of the electrolysis device 10, avoiding blockage of the water pipe 700 that could affect the disinfection and / or cleaning effects, thus demonstrating good practicality. In one embodiment, the protective tube element 800 can be a spring to increase the rigidity of the water pipe 700 while ensuring its flexibility, thereby preventing bending during use. In another embodiment, the protective tube element 800 can also be a spring sleeve, etc., and the present disclosure does not limit this. It should be noted that the provision of a protective element 800 on at least a portion of the water pipe 700 in this disclosure means that the entire water pipe 700 is fitted with a protective element 800; or, a portion of the water pipe is fitted with a protective element 800. There may be only one protective element 800, or multiple protective elements 800 may be provided at intervals. Furthermore, the protective element 800 may be provided on the water pipe 700 connected to the inlet 101, on the water pipe 700 connected to the outlet 102, or on both the water pipe 700 connected to the inlet 101 and the water pipe 700 connected to the outlet 102. This disclosure does not impose any limitations on this.

[0052] Based on the aforementioned electrolysis device 10, this disclosure also provides a cleaning device. This cleaning device includes the aforementioned electrolysis device 10. The cleaning device having the aforementioned electrolysis device 10 can output cleaning water of uniform concentration through the electrode assembly 200 within the electrolysis device 10, resulting in good disinfection effect without increasing the user's burden or cost, thus improving the user experience and demonstrating excellent practicality.

[0053] Figure 12 shows a schematic diagram of a cleaning device according to some embodiments of the present disclosure. Referring to Figure 12, the cleaning device also includes a water tank 20 and a pump body 30. The water tank 20 is used to hold cleaning water. The water tank is in fluid communication with the electrolysis device. The pump body is configured to allow cleaning water to enter the electrolysis device through the inlet 101 and to allow cleaning water to flow out of the electrolysis device through the outlet 102; this configuration allows cleaning water to be input into the tank of the electrolysis device 10 by the operating pump body during use of the cleaning device, and to be electrolyzed into at least one disinfecting agent under the action of the energized electrode assembly. It should be noted that the flow rate of the cleaning water from 0 to 300 mL / min encompasses multiple operating states of the cleaning device. In some embodiments, when the cleaning device performs surface cleaning, the flow rate of the cleaning water at the outlet 102 ranges from 0 to 100 mL / min. At a flow rate of 0 mL / min, the cleaning equipment pre-prepares electrolyzed water for surface cleaning; surface cleaning is performed at a flow rate of 0 to 100 mL / min (excluding 0 mL / min); when the cleaning equipment performs self-cleaning, the flow rate of the cleaning water at outlet 102 ranges from 0 mL / min to 100 to 300 mL / min; at a flow rate of 0 mL / min, the cleaning equipment pre-prepares electrolyzed water for equipment self-cleaning; and equipment self-cleaning is performed at a flow rate of 100 to 300 mL / min. Furthermore, the flow rate range of the cleaning water at outlet 102 for both surface cleaning and equipment self-cleaning is not limited to the above ranges. In other embodiments, the flow rate range of the cleaning water at outlet 102 may be set from 0 to 150 mL / min when the cleaning equipment performs surface cleaning, and from 150 to 300 mL / min when the cleaning equipment performs self-cleaning, etc. According to the structural design of the electrolysis device according to some embodiments of the present disclosure, disinfectant factors can be fully prepared in the flow rate range of 0~300mL / min, so that the cleaning equipment can disinfect the surface to be cleaned or the cleaning equipment itself.

[0054] Referring to Figure 12, the cleaning equipment also includes a water distributor 40 and a cleaning component 50; the water tank 20, the electrolysis device 10, and the water distributor 40 are sequentially fluidly connected. A pump body 30 is located between the water tank 20 and the electrolysis device 10; or, between the electrolysis device 10 and the water distributor 40.

[0055] In one embodiment, the cleaning device includes, but is not limited to, robots such as robotic vacuum cleaners, robotic mops, or robotic vacuum and mop combos, or handheld surface cleaning devices such as floor scrubbers. All of these components are housed within the robot or floor scrubber. In another embodiment, the cleaning device includes a robot and a base station that work together. A water tank is located within the base station, while an electrolysis unit is located within the robot, which supplies cleaning water to the robot. This allows for disinfection not only during robot cleaning or self-cleaning but also when the robot changes water or washes its mop within the base station.

[0056] The electrolysis device provided in this disclosure includes a housing with an inlet and an outlet. Cleaning water can be injected into the housing through the inlet and discharged from the outlet at a flow rate of 0-300 mL / min. Since the electrode assembly is located within the housing, the cleaning water can cover the surface of the electrode assembly. When the electrode assembly is energized, it electrolyzes the cleaning water in the housing to produce at least one disinfectant. This disinfectant, along with the cleaning water, is sprayed from the outlet to clean the surface. This allows the cleaning equipment to disinfect without the need to add disinfectant to the water tank, ensuring a consistent disinfection concentration and effective disinfection. Therefore, it does not increase the user's burden or cost, thus improving the user experience.

[0057] In addition, since the first electrode element is connected to the second electrode element and / or the third electrode element is connected to the second electrode element to electrolyze the cleaning water, the first electrode element can be connected to the second electrode element and / or the third electrode element can be connected to the second electrode element according to the cleaning environment to electrolyze different disinfection factors, thereby improving the disinfection effect.

[0058] Cleaning equipment equipped with the above-mentioned electrolysis device can output clean water of uniform concentration through the electrode assembly inside the electrolysis device, which has a good disinfection effect without increasing the user's burden and cost; it can also ensure that the clean water can smoothly enter and exit the electrolysis device, ensuring the disinfection and / or cleaning effect, thereby improving the user experience and having great practicality.
